Description

Technical Field

[0001] The invention relates to the field of soil sampling equipment, and in particular to a sampling vehicle device for land resource management and a use method thereof. Background Art

[0002] Land resources refer to the general term for various natural resources within the land area of ​​the earth's surface that are given by nature and developed and utilized through human social and economic activities to produce ecological, economic and social benefits. In land resource management, it is necessary to collect samples of soil, rocks, vegetation cover and other surface materials through sampling vehicles for laboratory analysis or on-site testing, so as to obtain detailed information on land quality, nutritional status, pollution level and ecological health status, in order to facilitate land resource management.

[0003] The existing sampling vehicle device is basically composed of a trolley, a multi-stage telescopic cylinder and a sampler. The sampler is basically a cylindrical object, which is used to sample and collect soil, so that the staff can analyze the data of the soil taken out from the sampler. When the sampling of land resources is needed, the staff moves the multi-stage telescopic cylinder and the sampler to the sampling area through the trolley, and then the multi-stage telescopic cylinder drives the sampler to move downward, drives the sampler into the soil, and then the multi-stage telescopic cylinder drives the sampler to reset, so that the sampler leaves the soil. Inside, the land resource sampling work is completed, but when the multi-stage telescopic cylinder drives the sampler to move downward, the direct collision between the sampler and the soil will generate a significant impact force. This force is not only limited to the sampler itself, but will also be quickly transmitted to the entire equipment frame along the multi-stage telescopic cylinder structure, causing the equipment to shake. The shaking will also cause structural damage to the soil sample. The originally tight soil layer may become loose due to external force during the sampling process, or even mixed with soil of different layers, changing the original state of the sample and seriously affecting the accuracy of subsequent analysis.

[0004] Therefore, it is necessary to provide a new sampling vehicle device and use method for land resource management to solve the above technical problems. Summary of the invention

[0014] A method for using a sampling vehicle device for land resource management specifically comprises the following steps:

[0015] Step 1: Move the equipment. The staff manually pushes the trolley to move it, so that the trolley drives the multi-stage telescopic cylinder and the sampler to move through the support platform, so that the sampler moves to the land where sampling is required;

[0016] Step 2: Sampling is stable. The staff starts the multi-stage telescopic cylinder to drive the sampler to move downward. The sampler drives the two movable blocks and the two square blocks to retract through the inclined surfaces of the two first arc blocks and the inclined surfaces of the two second arc blocks, respectively, so that the two first arc blocks drive the two first springs to be in a compressed state through the two movable blocks. At the same time, the sampler drives the two second arc blocks to be in a compressed state through the two square blocks. The extended end of the multi-stage telescopic cylinder drives the sampler to enter the soil for sampling. The two first arc blocks and the two second arc blocks are distributed in a ring shape around the sampler and the extended end of the multi-stage telescopic cylinder. The two first arc blocks and the two second arc blocks improve the stability of the sampler entering the soil for sampling through the extended end of the multi-stage telescopic cylinder.

[0017] The equipment is stable. When the two movable blocks drive the two first springs to be in a compressed state, the two movable blocks drive the two connecting blocks to move inside the connecting groove, so that the two connecting blocks drive the two triangular blocks to move, and the two triangular blocks drive the two trapezoidal blocks to move downward. At the same time, the two trapezoidal blocks drive the third springs to be in a compressed state through the blocking blocks respectively, and the trapezoidal blocks drive the two ground nails to move downward, so that the two ground nails are inside the ground, thereby improving the stability of the equipment.

[0018] Step three, sampling reset, the staff drives the multi-stage telescopic cylinder to reset, so that the extended end of the multi-stage telescopic cylinder drives the sampler to move upward, so that the sampler performs a reset movement, when the extended end of the multi-stage telescopic cylinder drives the sampler to leave the two first arc blocks and the two second arc blocks, the two first arc blocks and the two second arc blocks respectively release the drive of the two first springs and the two second springs through the two movable blocks and the two square blocks, according to the stretchability of the springs, the two first springs and the two second springs respectively drive the two first arc blocks and the two second arc blocks through the two movable blocks and the two square blocks to complete the closure of the circular groove, so as to prevent the soil collected inside the sampler from falling to the ground;

[0019] The equipment is reset. When the two first springs drive two of the arc blocks to extend through the two movable blocks, the movable block releases the drive to the triangular block through the connecting block, so that the triangular block releases the drive to the trapezoidal block. At the same time, the trapezoidal block releases the drive to the third spring through the blocking block. According to the stretchability of the spring, the third spring drives the trapezoidal block to move upward through the blocking block, so that the trapezoidal block drives the ground nail to leave the ground, completing the reset movement of the ground nail.

[0020] Compared with the related art, the sampling vehicle device and use method for land resource management provided by the present invention have the following beneficial effects:

[0021] 1. The present invention drives the two connecting blocks to move in the connecting grooves when the two movable blocks drive the two connecting blocks to move, and the two triangular blocks drive the two trapezoidal blocks to move downward. At the same time, the two trapezoidal blocks respectively drive the third spring to be in a compressed state through the blocking blocks, and the trapezoidal blocks drive the two ground nails to move downward, so that the two ground nails are inside the ground, thereby improving the stability of the equipment. The two ground nails are directly driven by the downward movement of the trapezoidal blocks to be firmly anchored in the ground to form a solid anchoring point, which significantly enhances the stability of the equipment, effectively reduces the shaking phenomenon when collecting soil samples under complex terrain, prevents the structural damage of the soil samples, and prevents the soil layer to be sampled from mixing into the soil of different layers, effectively avoids the introduction of non-target samples, and ensures the accuracy of the collected soil samples.

[0022] 2. In the present invention, when the staff starts the multi-stage telescopic cylinder, the multi-stage telescopic cylinder drives the sampler to move downward, and the sampler drives the two movable blocks and the two square blocks to retract through the inclined surfaces of the two first arc blocks and the inclined surfaces of the two second arc blocks, so that the two first arc blocks drive the two first springs to be in a compressed state through the two movable blocks, and at the same time, the sampler drives the two second arc blocks to drive the two second springs to be in a compressed state through the two square blocks, and the extended end of the multi-stage telescopic cylinder drives the sampler to enter the soil to perform sampling work, and the two first arc blocks and the two second springs are compressed. The two arc blocks are distributed in a ring shape around the sampler and the extended end of the multi-stage telescopic cylinder. The two first arc blocks and the two second arc blocks improve the stability of the sampler that enters the soil for sampling through the extended end of the multi-stage telescopic cylinder. Through the two first arc blocks and the two second arc blocks distributed in a ring shape, this structure provides dynamic support when the sampler enters the soil, ensuring the verticality and stability of the sampler, and effectively avoiding the deviation and tilt caused by uneven terrain or changes in soil hardness to a certain extent, thereby ensuring the consistency of the sampling depth and the representativeness of the samples.

[0023] 3. In the present invention, when the staff drives the multi-stage telescopic cylinder to reset, the extended end of the multi-stage telescopic cylinder drives the sampler to move upward, so that the sampler performs a reset movement. When the extended end of the multi-stage telescopic cylinder drives the sampler to leave between the two first arc blocks and the two second arc blocks, the two first arc blocks and the two second arc blocks release the drive of the two first springs and the two second springs through the two movable blocks and the two square blocks respectively. According to the elasticity of the springs, the two first springs and the two second springs drive the two first arc blocks and the two second arc blocks through the two movable blocks and the two square blocks to complete the closure of the circular groove, thereby preventing the soil collected inside the sampler from falling to the ground. Through this structure, when the sampler completely leaves the arc block area, the first spring and the second spring can effectively drive the two first arc blocks and the two second arc blocks to accurately close the circular groove through the linkage of the movable block and the square block by virtue of their inherent elasticity, thereby forming an effective barrier, thereby preventing the soil sample from falling into the soil to a certain extent due to the vibration of the multi-stage telescopic cylinder when it is stopped after the reset is completed.

[0043] A second spring 9 is fixedly arranged on the opposite side of the two square blocks 7 and the two square grooves 6, and the extended end of the sampling mechanism slides and extends out of the circular groove 3.

The blocking block 17 limits the trapezoidal block 14 through the limiting groove 16 of the limiting block 15 to prevent the trapezoidal block 14 from separating from the limiting block 15 and prevent the trapezoidal block 14 from angular displacement during movement.

[0046] like Fig.11 as well as Fig.12 As shown, a method for using a sampling vehicle device for land resource management specifically includes the following steps:

[0047] Step 1: Equipment movement: The staff manually pushes the trolley 1 to move, so that the trolley 1 drives the multi-stage telescopic cylinder 22 and the sampler 23 to move through the support platform 21, so that the sampler 23 moves to the land where sampling is required;

[0048] Step 2, sampling is stable. The staff starts the multi-stage telescopic cylinder 22, so that the multi-stage telescopic cylinder 22 drives the sampler 23 to move downward. The sampler 23 drives the two movable blocks 5 and the two square blocks 7 to retract through the inclined surfaces of the two first arc blocks 2 and the inclined surfaces of the two second arc blocks 25, so that the two first arc blocks 2 drive the two first springs 8 to be in a compressed state through the two movable blocks 5. At the same time, the sampler 23 drives the two second arc blocks 25 to be in a compressed state through the two square blocks 7. The extended end of the multi-stage telescopic cylinder 22 drives the sampler 23 to enter the soil for sampling. The two first arc blocks 2 and the two second arc blocks 25 are distributed in a ring around the sampler 23 and the extended end of the multi-stage telescopic cylinder 22. The two first arc blocks 2 and the two second arc blocks 25 improve the stability of the sampler 23 entering the soil for sampling through the extended end of the multi-stage telescopic cylinder 22.

[0049] Through the two first arc blocks 2 and the two second arc blocks 25 distributed in a ring shape, the structure provides dynamic support when the sampler 23 enters the soil, ensures the verticality and stability of the sampler 23, and effectively avoids the deviation and tilt caused by uneven terrain or changes in soil hardness, thereby ensuring the consistency of sampling depth and the representativeness of the sample. Specifically, when the sampler 23 tilts, it will drive the protruding end of the multi-stage telescopic cylinder 22 to tilt, and then the protruding end of the multi-stage telescopic cylinder 22 drives the first arc block 2 or the second arc block 25 to tilt, so that the first arc block 2 drives the movable block 5 to tilt inside the movable groove 4 and contact the side wall of the movable groove 4, so that the movable block 5 uses the force of the equipment to limit the protruding end of the multi-stage telescopic cylinder 22 by the first arc block 2, and similarly, the second arc block 25 drives the square block 7 to tilt inside the square groove 6 and contact the side wall of the movable groove 4, so that the square block 7 uses the force of the equipment to limit the protruding end of the multi-stage telescopic cylinder 22 by the first arc block 2;

[0050] The equipment is stable. When the two movable blocks 5 drive the two first springs 8 to be in a compressed state, the two movable blocks 5 drive the two connecting blocks 11 to move inside the connecting groove 10, so that the two connecting blocks 11 drive the two triangular blocks 12 to move, and the two triangular blocks 12 drive the two trapezoidal blocks 14 to move downward. At the same time, the two trapezoidal blocks 14 drive the third springs 18 to be in a compressed state through the blocking blocks 17 respectively, and the trapezoidal blocks 14 drive the two ground nails 24 to move downward, so that the two ground nails 24 are inside the ground, thereby improving the stability of the equipment;

[0051] By driving the two ground spikes 24, the ground spikes 24 are driven into the soil in a stable and controllable manner to form a solid anchor point, which significantly enhances the stability of the equipment, effectively reduces the shaking phenomenon when collecting soil samples in complex terrain, and ensures the accuracy and reliability of the sampling process;

[0052] Step 3, sampling reset, the staff drives the multi-stage telescopic cylinder 22 to reset, so that the extended end of the multi-stage telescopic cylinder 22 drives the sampler 23 to move upward, so that the sampler 23 performs a reset movement, when the extended end of the multi-stage telescopic cylinder 22 drives the sampler 23 to leave the two first arc blocks 2 and the two second arc blocks 25, the two first arc blocks 2 and the two second arc blocks 25 respectively release the drive of the two first springs 8 and the two second springs 9 through the two movable blocks 5 and the two square blocks 7, according to the stretchability of the springs, the two first springs 8 and the two second springs 9 respectively drive the two first arc blocks 2 and the two second arc blocks 25 through the two movable blocks 5 and the two square blocks 7 to complete the closure of the circular groove 3, so as to prevent the soil collected inside the sampler 23 from falling to the ground;

[0053] After the sampler 23 completely leaves the arc block area, the first spring 8 and the second spring 9, with their inherent stretchability, drive the two first arc blocks 2 and the two second arc blocks 25 to accurately close the circular groove 3 through the linkage of the movable block 5 and the square block 7, forming an effective barrier to prevent the soil sample from falling into the soil due to the vibration of the multi-stage telescopic cylinder 22 when it is reset;

[0054] The equipment is reset. When the two first springs 8 drive two of the arc blocks to extend through the two movable blocks 5, the movable block 5 releases the drive to the triangular block 12 through the connecting block 11, so that the triangular block 12 releases the drive to the trapezoidal block 14. At the same time, the trapezoidal block 14 releases the drive to the third spring 18 through the blocking block 17. According to the stretchability of the spring, the third spring 18 drives the trapezoidal block 14 to move upward through the blocking block 17, so that the trapezoidal block 14 drives the ground nail 24 to leave the ground, completing the reset movement of the ground nail 24.

8. A method for using a sampling vehicle device for land resource management, applicable to the sampling vehicle device for land resource management according to any one of claims 1 to 7, characterized in that: The specific steps include: Step 1: moving the equipment. A staff member manually pushes the trolley (1) to move the trolley (1) so that the trolley (1) drives the multi-stage telescopic cylinder (22) and the sampler (23) to move through the support platform (21), so that the sampler (23) moves to the land where sampling is required; Step 2: The sampling is stable. The staff starts the multi-stage telescopic cylinder (22), so that the multi-stage telescopic cylinder (22) drives the sampler (23) to move downward. The sampler (23) drives the two movable blocks (5) and the two square blocks (7) to retract through the inclined surfaces of the two first arc blocks (2) and the inclined surfaces of the two second arc blocks (25), so that the two first arc blocks (2) drive the two first springs (8) to be in a compressed state through the two movable blocks (5). At the same time, the sampler (23) drives the two second arc blocks (25) to retract. The two second springs (9) are driven to be in a compressed state by two square blocks (7), and the extended end of the multi-stage telescopic cylinder (22) drives the sampler (23) to enter the soil to perform sampling. The two first arc blocks (2) and the two second arc blocks (25) are distributed in a ring shape around the sampler (23) and the extended end of the multi-stage telescopic cylinder (22). The two first arc blocks (2) and the two second arc blocks (25) improve the stability of the sampler (23) that enters the soil to perform sampling through the extended end of the multi-stage telescopic cylinder (22); The device is stable. When the two movable blocks (5) drive the two first springs (8) to be in a compressed state, the two movable blocks (5) drive the two connecting blocks (11) to move inside the connecting groove (10), so that the two connecting blocks (11) drive the two triangular blocks (12) to move, and the two triangular blocks (12) drive the two trapezoidal blocks (14) to move downward. At the same time, the two trapezoidal blocks (14) drive the third springs (18) to be in a compressed state through the blocking blocks (17), and the trapezoidal blocks (14) drive the two ground nails (24) to move downward, so that the two ground nails (24) are inside the ground, thereby improving the stability of the device. Step 3: sampling reset, the staff drives the multi-stage telescopic cylinder (22) to reset, so that the extended end of the multi-stage telescopic cylinder (22) drives the sampler (23) to move upward, so that the sampler (23) performs a reset movement. When the extended end of the multi-stage telescopic cylinder (22) drives the sampler (23) to leave the two first arc blocks (2) and the two second arc blocks (25), the two first arc blocks (2) and the two second arc blocks (25) respectively release the drive of the two first springs (8) and the two second springs (9) through the two movable blocks (5) and the two square blocks (7). According to the stretchability of the springs, the two first springs (8) and the two second springs (9) respectively drive the two first arc blocks (2) and the two second arc blocks (25) through the two movable blocks (5) and the two square blocks (7) to complete the closure of the circular groove (3), so as to prevent the soil collected inside the sampler (23) from falling to the ground; The device is reset. When the two first springs (8) drive two of the arc blocks to extend through the two movable blocks (5), the movable block (5) releases the drive on the triangular block (12) through the connecting block (11), so that the triangular block (12) releases the drive on the trapezoidal block (14). At the same time, the trapezoidal block (14) releases the drive on the third spring (18) through the blocking block (17). According to the stretchability of the spring, the third spring (18) drives the trapezoidal block (14) to move upward through the blocking block (17), so that the trapezoidal block (14) drives the ground nail (24) to leave the ground, thereby completing the reset movement of the ground nail (24).
